2.1 General
MMA series welding machine applies the most advanced inversion technology in the world.
The appearance of the invert arc welding machine comes after the invert power theory and
components. The principle of the technology is to transform the power frequency of 50Hz/60Hz into
direct current and invert it into high frequency (33KHz) through high-power device IGBT, then
perform voltage-drop and commutation with the output high-power D.C power supply via full digital
Pulse Width Modulation (PWM) control technology. Since the switch power inversion technology is
adopted, the weight and volume decrease greatly while the conversion efficiency increase for more
than 30%.
Our welding power source can offer stronger, more concentrated and more stable arc. When the
welding rod and work piece get short circuit, its response will be quicker. It means that it is easy to
design welding machine with different dynamic characteristics, and it can even adjust the
characteristics to make arc softer or harder.
Under MMA mode, the machine has slope characteristic. The welding current, push current and
heat arc initiation current is set by the same knob synchronously, which makes good performance
of arc initiation, stable power output, welding shape and internal quality.
MMA series welding machine is widely used to weld different materials, such as carbon steel,
stainless steel, alloy steel, copper, non-ferrous metal, etc. It can apply to different electrode,
including acid electrode, basic electrode and cellulose electrode. Compared with the other
products, it has advantages of light, handy, easy to installation and operation, efficient and energy
saving. The conversion rate is above 85%. It applies for higher levels welding, field work and
indoors operation.
Thanks for purchasing our products and looking forward to your precious advice, we will try our
best to perfect our products and service.
The machine is mainly used in industrial fields. It will cause radion interference if used
indoors. Please take through precaution measures.
